WORK-BENCH CLAMP.

SPECIFICATION forming part of Letters Patent No. 756,137, dated March 29, 1904.

n Application filed September 4, 1903. Serial No. 171,979. (No model.)

To @ZZ whom, it may concern:

Be it known that'I, JOSEPH PENO, a citizen of the United States, residing at Oswego, in the county of Oswego and State of New York, have invented certain new and useful Improvements in Work-Bench Clamps; and I do hereby declare the following to be a full, clear, and eX- act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to an improvement in clamps for'work-benches, and resides in the production of a simple inexpensiveclamp designed for adjustable connection with the 'bench in a manner to permit its ready removal when not desired for use.

Fig. 2. Fig. 5 is a section on line y y, Fig. 2.

Referring to the accompanying drawings, 1

' represents a work-bench, in arecess 2 of which I secure 'my clamp-track 3, the latter being preferably of metal and secured in the however, so that'its upper edge is flush with the surface ofthe work-bench. y.

My improved clamp comprises a base-plate 4, having an inturned lip 5 at the upper end and a depending locking-block 6. The plate 4 is of a size to support the operating parts and in use overlies the track 3, with the block 6 resting in said track. The block is set at an angle, as shown, so that when the baseplate is at right angles to the track the sharp edges of the block'will contact with the opposite walls of thetrack. This arrangement permits the base-plate to be turned slightly to one side to entirely free the block 6 from the walls of the track, when lengthwise adjustment of the plate or its ready removal from the track may be'accomplished.

7 represents what I term the grippingplate, being pivoted at 8v to the base-plate and having its upper edge slidably held beneath the lip 5, as shown. The upper lateral edge of plate 7 projects beyond the edge of the base-plate and is formed with teeth 9, designed to enter and hold the material to be worked in the usual manner. The lower lat'- eral edge of plate 7 overlies the track 3 and projects beyond the edge of base-plate 4, said projecting portion being provided with a depending lug or post lO, normally within the track and contiguous one wall, as shown in dotted lines in Fig. 1.

11 represents a handle eccentrically pivoted at 12 to the base-plate and designed in operation to beark against the gripping-plate 7. The movement of the handle toward locking position (shown in Fig. 1) moves the upper portion of the gripping-plate toward the right, forcing the teeth 9 into the material and at the same time forces the lower portion of the plate 7 'toward the left, forcing the lug 10 into binding contact with one vwall of the track, and consequently forcing the upper ortopv edge of block '6 into contact with the opposite wall of the track, thus securely locking the clamp in position. Areverse movement of the handle loosens the parts and permits the lengthwise adjustment of the clamp or its removal, as devsired. recess 1n any desired manner, preferably, j

In holding large and heavy material it may be found desirable to provide the clamp with additional'locking means, and therefore I can provide, as shown in Figs. 2 and 3, a'second lock, comprising a disk 13eccentrically pivoted to one end of block 6 and having a handle 14: projecting beyond the track. Moving the handle downward will force the disk into binding engagement with the track, operating to hold the clamp in addition to the locking means above described.

If. desired, my clamp can be used in connection with the form of bench-dog illustrated in Fig. 5, in which 15 represents a'nut or baseblock seated iiush in the work-bench and formed with a central threaded opening 16. The dog proper comprises a plate 17, having theusual holding-teeth 18 on opposite sides, Xed to a depending threaded stud 19, designed for engagement with the opening 16.

Ihe dog of my construction is readily adjustable in a vertical direction and may be quickly removed when desired.

It Will be noted that two sides of the dog proper are plain-that is, Without teeth-by Which provision is made to hold Wood or other material Without marring the edge, as is desirable in fine cabinet-Work and repairing. If desired, means can be provided to rest between the teeth 9 and the Work to prevent marring of the Work by the teeth.

It Will benoted that my clamp is readily placed in position in the track or other suitable guide or slide Way when desired, may be quickly and conveniently adjusted as needed, and is readily removable.

The track, guide, or slide Way can be formed of any suitable cross-sectional shape or form and can be arranged Wherever my clamp is adapted for application, and it is evident that various modifications might be resorted to Without departing from the spirit and scope of my invention, and hence I do not Wish to limit my invention to the exact showing herein.

Having thus described my invention, what I claim is l. A support having a guide or a slide Way, in combination with a clamp extending into and normally free to move along said Way and carrying and provided with a swinging movable gripping member, and member-actuating and locking-lever means carried by and movable with said clamp to advance said gripping member to gripping position and simultaneously lock the clamp in the Way.

2. A support having a guide or slide Way, in combination with a clamp normally free to move along said Way and comprising a base overlapping and having a portion extending into said Way and an independently-movable gripping member carried by said base and having a portion in said Way, and means independently mounted on and carried by said base to advance said member to gripping position and to lock the same in said position.

3. In combination With a Work-bench having a depressed track, of a bench-clamp comprising a base-plate overlying the track and having a block depending in the track, a gripping-plate pivoted to the base-plate and having a stud depending in the track, and means to move the gripping-plate to bind the stud and block against opposite Walls of the track.

4. In combination With a Work-bench having a depressed track, of a bench-clamp comprising a base-plate overlying and having a block depending in the track, a gripping-plate pivoted to the base-plate and having a stud depending in the track and a handle to move the gripping-plate to bind the stud and block against opposite Walls of the track.

5. In combination with a work-bench having a depressed track, of a clamp having a block depending in the track, a gripping-plate having a stud depending in the track, means to move the gripping-plate to bind the stud and block against opposite Walls of the track, and means carried by the block operative to impinge one Wall of the track.

6. In combination with a Work-bench having a depressed track, of a clamp having a block depending in the track, a gripping-plate having a stud depending in the track, means to move the gripping-plate to bind the stud and block against opposite Walls of the track, and an eccentric disk carried by the block and movable to impinge one Wall of the track.

7 In combination with a support having a depressed track, of a base-plate overlying said track and having a block depending in the track, a gripping-plate pivoted tothe baseplate and having a stud depending in the track, said gripping-plate being formed with a series of gripping-teeth, and means to advance the gripping-teeth and simultaneously bind the block and stud against the Walls of the track.
